Looking at https://github.com/ovn-kubernetes/ovn-kubernetes/actions/runs/11756667770/job/32753396792?pr=4827 It seem that the tests fails on checking pod connected to UDN is able to reach KAPI ovn-kubernetes/ovn-kubernetes/test/e2e/network_segmentation.go:357 This issue wont seem to reproduce on local env, I tried to run it continually using Ginkgo unti-it-fails option. I couldn't find something related to the fact the test use the CUDN CRD yet.
